Gopal V commented on HIVE-13818:
--------------------------------
This specific case looks like it internally confuses an {{int:int}} join asa a
{{long:long}} join.
Both are handled by same vector ops for joins, but need different ser/deser
codepaths when reading off the SerDe into the LongColumnVector.
There's no real difference once the deserialization is complete.
> Fast Vector MapJoin not enhanced to use sortOrder when handling
> BinarySortable keys for Small Table?
